STOVEPIPE ANCHOR OR LOCK.

Specification of Letters Patent.

Patented May 9, 1922.

Application filed November 17, 1917, Serial No. 202,669. Renewed March30, 1922. Serial No. 548,190.

To all whom it may concern:

Be it known that I, JosnrI-r E. DAMAN, a citizen of the United States,residing at St. Louis, in the county of Gratiot and State of Michigan,have invented new and useful Improvements in Stovepipe Anchors or Locks,of which the following is a specification.

This invention relates to improvements in a flue pipe :for stoves, andan object of the invention is to provide a simple and effective meansfor sustaining a pipe in the flue opening in the chimney.

WVith the above and other objects in view, the improvement resides inthe construction, combination and arrangement oi": parts set forth inthe following specification and falling within the scope of the appendedclaim.

In the drawing:

Figure 1 is a fiue pipe constructed in accordance with the presentinvention, and illustrating the same applied, the chimney being shown.partly in section,

Figure 2 is a longitudinal sectional view, and

Figure 3 is a transverse sectional view apthe same is provided with alongitudinal opening that is normally closed by a hinged door 4, thesaid door having its edge opposite that provided with the hinge formedwith a spring catcho for normally retaining the door in closed position.By this means it will be noted that access may be obtained to the pipe 3so that soot may be readily removed therefrom.

The end of the pipe received in the flue opening 2 is tapered, asindicated by the numeral. 6. Having their inner ends secured in thepipe, inward of the tapered end 6 thereof, is a plurality of angularlydisposed flat spring plates 7, which project through the reduced end ofthe pipe. These spring plates in their outer portion are slittedlongitudinally and transversely, the transverse slit being arranged inthe end of the p pe 3, and the metal bounded by the slits being bent orrounded outwardly providing a plurality of spring-gripping elements ortongues 8. The tongues 8 are designed for frictional contact with thepipe opening in the flue and the inner ends of the said tongues arelimited in an outward direction by contacting with the flared or taperedend 6 of the pipe 3.

Arranged upon the pipe 3 adjacent to the tapered end thereof is a collarmember 9, and the inner face of this collar member which is adapted tocontact with the chimney breast is provided with a facing ofcompressible fire-proof material 10, such as, for instance, asbestos.

The pipe 3 at a suitable distance from its tapered end has securedthereto spaced straps 11 bent upon themselves to provide eyes 13 andsecured to the pipe by elements 12, In one of the eyes is the end of acoil spring 1st which surrounds the pipe and which is adapted to exert apressure against the collar 9 to force the same into contact with thechimney breast. It is, 01 course, to be understood that the spring 14 iscomparatively weak; that is, the said spring is of a less strength thanthe spring fingers which engage with the wall provided bythe opening inthe chimney breast, the function of the spring 1-1 being merely to forcethe collar 9 and its fireproof facing at all times into contact with thechimney breast.

The eye members 13 are employed to facilitate the connection. 0f thespring 14 to the pipe section 3, only one eye member in reality beingnecessary. The spring plates 7 have their inner ends secured to the pipesection 3, and the remaining portion of the said plates is free ofconnection with the said pipe section. The plates are of springmaterial, and consequently will exert a pressure in an outwarddirection, or against the flared end of the pipe section. The curved orrounded tongues 8 have their inner ends arranged inward oi the flaredend of the pipe section. 3, and consequently contact with the innersurface of the said flared end. The curved spring members 8 are assistedin their contacting engagement with the wall of the pipe opening by thebody of the spring members 7 and consequently will effectively retainthe end of the pipe section in the said opening. However, the ends ofthe tongues being arranged inward of the flared end of the pipe sectionwill permit the ready withdrawal of the said section from the pipeopening.

Having thus described the invention, what I claim is:

A means for holding a stove pipe in a chimney flue opening, comprising,in combination with a stove pipe having a tapered end to be received inthe flue opening, longitudinally arranged spaced fiat spring plateshaving their inner ends secured in the pipe inward of the tapered endthereof and their outer ends extending through the tapered end, and saidspring plates having each an In testimony whereof I afiix my signature.20

JOSEPH E. DAMAN.
